"I think we are going to crush them everywhere," McConnell said about Tea Party challengers in a New York Times interview published Saturday. "I don’t think they are going to have a single nominee anywhere in the country."

McConnell faces a primary challenge from the right. The Senate Conservatives Fund, which backs Tea Party challenger Matt Bevin, believes the candidate has a chance of defeating McConnell the the primary.

"Mitch McConnell is clearly in trouble in this primary or he wouldn’t be attacking Matt Bevin and declaring war on conservatives," Matt Hoskins, the head of the SCF, told the New York Times.
